Pharmaceutical and personal care products (PPCPs) constitute a broad class of organic compounds, some of which belong to the list of the OECD high production volume (HPV) chemicals. These compounds have emerged as environmental ...

The incidences of diarrhoeal episodes in infants and children have mostly been associated with
the consumption of contaminated weaning foods. This is especially true in developing
countries where factors such as the lack ...

Dyes are often recalcitrant organic molecules that produce a colour change and contribute to the organic load and toxicity of textile industrial wastewater. Untreated effluent from such sources is harmful to aquatic life ...

Rehabilitation of landfill sites is important for successful land utilization. Revegetation is
one key element of the process since it can overcome aesthetic problems. The inimical
challenges of landfill leachate and gas ...

The need to develop a renewable, environmentally friendly source of energy has become a primary focus in modern science, with bio gas showing considerable potential. Interest in the methanogenic Archaea has therefore grown ...

Aeromonas spp. isolates, which are fish and opportunistic human pathogens, form biofilms, however the factors involved in and affecting biofilm formation have not been fully elucidated. Biofilm formation is affected by ...

The genus Bacillus is comprised of Gram-positive, rod-shaped, spore-forming bacteria which are
well known for their ability to produce a diverse array of antimicrobial compounds. Ofparticular
interest is the ability of ...

This study evaluated the efficacy of bioremediation as a treatment option for a
hydrocarbon and heavy metal contaminated soil. Microbial degradation of
hydrocarbons under aerobic, nitrate-reducing and sulphate-reducing ...

Darvill Wastewater Works (DWWW) receives and treats both domestic and industrial wastewater from the city of Pietermaritzburg, in KwaZulu-Natal. Sludge from the wastewater treatment is sprayed onto surrounding lands, causing ...

Microorganisms are increasingly used in toxicological studies to determine potential
environmental impacts of xenobiotic compounds. A multi-stage laboratory model was developed
to facilitate the examination of environmental ...

Cereal crops such as maize and sorghum are economically important in South Africa (SA) as a staple food diet. In order to meet the needs of South Africa’s growing population, higher yields in crop production need to be ...

During fermentation, the yeast Saccharomyces cerevisiae produces a broad range of aroma-active esters that are important for the desirable complex flavour of beer. The sensory threshold levels of these esters in beer are ...
